[PATCH 2/3] char: tpm: constify attribute_group structures.

From: Arvind Yadav
Date: Wed Aug 02 2017 - 07:20:35 EST


attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.
